Hi, I am trying to run WRF-ARW in parallel. This is configuration of my system: ------------------------------------------------- Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: AuthenticAMD CPU family: 16 Model: 2 Stepping: 3 CPU MHz: 1150.000 BogoMIPS: 4587.84 Virtualization: AMD-V L1d cache: 64K L1i cache: 64K L2 cache: 512K L3 cache: 2048K NUMA node0 CPU(s): 0-3 -------------------------------------------------
When I start wrf with mpirun -np 4 ./wrf.exe, I get this: ------------------------------------------------- starting wrf task 0 of 1 starting wrf task 0 of 1 starting wrf task 0 of 1 starting wrf task 0 of 1 ------------------------------------------------- This indicates that it is not using 4 processors, but 1. Any idea what might be the problem? Thanks, Djordje
